What should I start off saying to this girl?

<> this maybe a little long<>. Ok if you read my old question. You should know that am thinking about trying to get with this girl. Well I decided I should at least try.( I might chicken out tho xd). Biggest problem is well I don’t know what I should say. I never try talking to a girl in my life. They alway came to me ( well I did once but I did it with text messages which is a lot more easier). Seriously I don’t even know her name. I think I heard the teacher say chances or something. But am not going to go up and start a talk in person. To many peoples like to be in other peoples business. And that how rumors start ect. Plus am not much of a talker anyway ( am more of a action guy :d). So I got to thinking ( I got the perfect excuses for this). Why not write a few notes.( what harm can that cause). And if she ask why I got 2 great excuses. #1. I don’t want other peoples in my business. #2. I gotta catch my work up so I don’t really have time during class to talk. Them so perfects ( if you can think of anything better let me know.). Now I got 2 bigger problem. What should I say. And how should I give her that note. Cause them peoples in that class got eyes like hawks. I really don’t really peoples in my business. Cause that how everything get mess up. I let my sister one time try to help me get with someone. And she mess it all up. That not the first time something like that happen. So am taking the safe road. So I really need some help here. Thank but am not even sure if ill be able to do it. Am a coward. Well maybe not but still. I don’t know how this gonna affect me. Now what if she tell everyone in school ect ect. Peoples will laughs at me for weeks. Then what if she already got a boyfriend. Am not a fighter. I can’t be getting beat up. I need a lot of advice everything need to go smooth. Thank -.- ( life is crazy)
